Young 'Twilight' Vampire Is Way Too Innocent for '50 Shades of Grey' Movie

Yeah -- so I know there's a huge rat race in Hollywood right now to land the major roles in theFifty Shades of Grey movie, but a line really has to be drawn on who is and who is definitely not an acceptable option for any of the leading parts.

Never say never? Um, I think Dakota has to say never when it comes to anything erotic. Take a moment and try and picture her being tied to a bed post, spanked, or in any sort of sexual scene, for that matter. Let me guess -- you can't do it, can you? It's because her sweet and innocent image is permanently burned into our brains and simply can't be erased.

There's absolutely no way she can be cast as Ana, and even Kate's role is way too much of a stretch. Dakota can't even associate with a sex-crazed submissive let alone play one herself. (It just isn't right.)
